Arsenal manager Arsene Wenger does not believe English football has a "hooligan problem" and has called for a return to safe standing at stadiums.
Crowd trouble marred West Ham's EFL Cup fourth-round home win over Chelsea on Wednesday.
Wenger, 67, was "surprised" at the disorder, as "in England we're not used to facing these problems any more".
"You cannot say 200 people is a general problem in the country," said Wenger, who has managed Arsenal since 1996.
"Hopefully West Ham will get rid of the problem very quickly. I am in favour of the resurgence of standing behind the goals and that is not a good advert to come back to standing.
